Celiac diagnosis while in college?

For the past year and a half, since I had viral bronchitis during a high-stress period, I have been dealing with these problems:

- constipation, especially after eating bread/bread products or beer

- sharp abdominal pains in times of high stress

- headaches

- mood swings

- digestive pain after eating bread and beer

Do these symptoms sound like celiacs do you? I am currently a college student at an out-of-state school and will not meet with my primary care physician for a month and my gastroenterologist for two and a half months.

If this does sound like celiacs, should I ask my primary care doctor to do the tests or wait until I see the GI specialist? How long does the diagnosis process normally take?

Thanks in advance!
